ABSTRACT:
A mechanical lock for an airplane engine thrust reverser is connected to an actuator for the thrust reverser sleeve. The mechnical lock includes an electrically operated solenoid which moves a locking pin between an unlocked position and a locked position. When the pin is in the locked position, it engages a toothed wheel which is mounted about a shaft which engages a drive gear for the thrust reverser actuator. In this manner, movement of the thrust reverser sleeve is prevented until commanded operation of the thrust reverser whereby the locking pin is moved to the unlocked position.
